One of the things that fascinates me about the annual Who Do You Think You Are? LIVE! exhibition in London is the large number of military exhibits and re-enactors. At this year's show, I had a chance to talk with Mark and Carl who were at the show along with a World War I British tank.
This is one of the very first tanks ever used in warfare. Mark and Carl described the life of the tank crews in combat.
This video gives you an insight to the sorts of displays available at this genealogy/history/military/archaeology exhibition.
